Abstract
An optical element including a substrate, a first optical film and a second optical film. The first optical film and the second optical film are disposed on at least one side of the substrate and are both formed on the substrate. The first optical film has a first surface facing away from the substrate and a plurality of first optical microstructures disposed on the first surface. The second optical film has a second surface facing away from the substrate and a plurality of second optical microstructures disposed on the second surface. The orthogonal projection of the first optical microstructures on the substrate does not overlap the orthogonal projection of the second optical microstructures on the substrate. A wafer level optical module adopting the optical element is also provided.
